"Every web designer or server administrator needs this book. From the moment I picked it up to read, I couldn't put it down. When I had finished reading it, I wanted to pick it up and start reading it a second time...I'm giving this book 5 STARS for the excellent advice that it gives on fine tuning every aspect of website administration."

"This book still scores highly on the sections which are general in their scope, particularly the new chapters which have been written for this edition. The more specific sections feel dates, and are likely to further age extremely quickly. Overall the book is still a good source for advice on identifying performance bottlenecks and suggesting ways to tune the infrastructure to eliminate them."

"If you want to squeeze the maximum performance from your web server, this book will help you make your web site sing...Everything from low volume sites (1-10,000 hits/day) to high (over 1 million hits/day) can benefit from this in-depth book. Techniques that may work well at lower traffic levels can fall apart once the server heats up. Killelea takes a pragmatic approach to performance tuning with an emphasis on actual testing and measurement rather than overplanning, mathematical modeling, and simple yet expensive solutions."
